Bifurcation Configuration Is an Independent Risk Factor for Aneurysm Rupture Irrespective of Location

open access: yesFrontiers in Neurology, 2019
Background: Bifurcation and sidewall aneurysms have different rupture risks, but whether this difference comes from the location of the aneurysm is not clear.

Global bifurcation result and nodal solutions for Kirchhoff-type equation

open access: yesAIMS Mathematics, 2021
We investigate the global structure of nodal solutions for the Kirchhoff-type problem $ \left\{\begin{array}{ll} -(a+b\int_{0}^{1}|u'|^2dx)u'' = \lambda f(u),\ x\in (0,1),\\[2ex] u(0) = u(1) = 0, \end{array} \right. $ where $ a > 0, b > 0

Bifurcation of homoclinics [PDF]

open access: yesProceedings of the American Mathematical Society, 2007
We show that homoclinic trajectories of nonautonomous vector fields parametrized by a circle bifurcate from the stationary solution when the asymptotic stable bundles of the linearization at plus and minus infinity are “twisted” in different ways.

Bifurcation analysis of a normal form for excitable media: Are stable dynamical alternans on a ring possible?

open access: yes, 2008
We present a bifurcation analysis of a normal form for travelling waves in one-dimensional excitable media. The normal form which has been recently proposed on phenomenological grounds is given in form of a differential delay equation.

Hopf-zero bifurcation of Oregonator oscillator with delay

open access: yesAdvances in Difference Equations, 2018
In this paper, we study the Hopf-zero bifurcation of Oregonator oscillator with delay. The interaction coefficient and time delay are taken as two bifurcation parameters. Firstly, we get the normal form by performing a center manifold reduction and using

Control Bifurcations [PDF]

open access: yesIEEE Transactions on Automatic Control, 2004
The article of record as published may be located at http://dx.doi.org/10.1109/TAC.2004.832199 A parametrized nonlinear differential equation can have multiple equilibria as the parameter is varied. A local bifurcation of a parametrized differential equation occurs at an equilibrium where there is a change in the topological character of the nearby ...

Significance of Ghost Orbit Bifurcations in Semiclassical Spectra

open access: yes, 1999
Gutzwiller's trace formula for the semiclassical density of states in a chaotic system diverges near bifurcations of periodic orbits, where it must be replaced with uniform approximations.

Onset of convection in a finite two-dimensional container due to unipolar injection of ions [PDF]

open access: yes, 2013
This work addresses the stability of a two-dimensional plane layer of a dielectric liquid enclosed in wall bounded cavities of different aspect ratios and subjected to unipolar injection of ions. Numerical simulations have been conducted to investigate
